LANDRUM. H. PELPHREY, OF GIRARD, KANSAS, ASSIGNOR OF FOR-TY-FIVE ONE-HUNDREDTHS TO U. G. PELPHREY, OF MULBERRY, KANSAS,

INLET-VALVE CASING.

Application filed October 21, 1919.

To all whom it may concern. I

Be it known that I, LANDRUM H. PELIH- an a citizen of the United Statesof America, residing at Girard, in the county of I W" I crawford andbtate 01 Kansas have invented new and useful Improvements in Inlet-Valve Casings, of which the following is a specification.

The object of the invention is to provide means in the nature of aprotector for the inlet or 'i'eed end of the suction pipe 01": a pump ofthe type'us d in connection with drainage work in mines and adapted tobe used. in lieu of a globe valve and also of a check valve and strainerfor preventing the induction of solid objects into the suction pipe ofthe pump.

Furthermore it is the object to provide a device for the purposeindicated which'can be constructed at comparatively small costand whichwill operate automatically in teeding the pump, maintaining itself inproper relation to the surface of the water in the mine and dispensewith the services of a helper or pump man ordinarily employed in thisconnection.

further objectsand advantagesoi the invention will appear in the courseoi the fol lowing description of a preferred embodiment, it beingunderstood that changes in term and proportion may be resorted to withinthe scope or" the claims without departing from rne principles involved.

In the drawing:

Figure is a side view of the feed nozzle.

Fig. 2 is a sectional view of the same.

ihe casing of the device preferably comprises the detachable couplingmember 10 and strainer member 11, the former of which is provided with athreaded terminal 12 for engagement with the end of the suction pipe ofthe pump (not shown) while the latter is connected with the former by athreaded joint 13 produced y forming an exteriorly threaded collar 141-on the strainer member to engage a corresponding opening in theSpecification of Letters Patent.

the pump which acts obviously in the direc tion indicated by the arrowin Fig. 2. The stem 17 the valve extends through the valveseat and aguide 18 at the outer side of the strainer member for attachment to aloat 19 by which the valve is normally held closed and the casingmaintained at a proper depth in the water in which it is submerged.

' 'lhelioat serves obviously to hold the eas- :111 in an uprightposition with the perforated wall of the strainer uppermost and near thesuriiace oi the water so as to avoid the induction of solid matter nearthe bot- 7 the outlet of the casing, and a float connected with tievalve for normally maintaining the same seated in opposition to thedirection of suction through the casing.

2. A protector for the suction pipes of pumps having its casing providedat the inlet end with a screen and at an intermediate point, between theinlet and outlet ends with a valve seat, and a float actuated checkvalve mounted for seating movement in a direction toward the inlet endof the casing.

3. A device for the purpose indicated havin casing provided withdetachable coupling and strainer members of which the former is providedwith means for engaging a suction pipe, and a float actuated valvemovable in the direction of flow through the casing and seatable towardthe inlet end thereof, the stem of said valve extending through andbeyond the strainer end of the casing. v

1. A device for the purpose indicated having a casing comprisingdetachable coupling and strainer members of which one is provided with athreaded collar for engagement with a corresponding recess in the other,a

valve seat being provided in said collar and a guide being provided inthe strainer member in axial alinement With said collar, and a floatactuated valve for engagement with said seat and adapted to close inOpposition to the flow of liquid through the casingend having its steinextended through said guide, thestminei' member being provided withliquid inlet epeniiigs in the portion of 10 its wall between said coilerand guide.

In testimony whereof I afiix my signature. LAN DRUM H. PELPHR-EY.
